LM137H/NOPB

The LM137H/NOPB is a 3-terminal adjustable Negative Regulator capable of supplying in excess of 1.5A over an output voltage range of -1.2 to -37V. These regulators are exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM137 series features internal current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads and serve a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation.
